B-Line Eaton series open racks, Universal spacing, Steel, Telco gray powder coat, 12-24 panel mounting holes, 51 mounting spaces, Top channel style,

Yes. The Eaton B-Line SB5858096UTG is a universal-spacing open frame rack with 12-24 tapped panel mounting holes, which is the standard thread for 19-inch EIA rack-mount gear. Universal hole spacing means the rail pattern repeats so any rack unit position can be used. You mount equipment directly with 12-24 screws, no cage nuts needed.

51 mounting spaces (rack units) on a frame that stands 96 inches tall. That is a full seven-foot-plus telco frame, enough for a complete network bay of switches, patch panels and cable management. Frame width is 23 inches and the bare rack weighs 81.71 lb, so plan floor loading and anchoring for the equipment weight on top of that.

The SB5858096UTG is built as a Seismic Zone 4 network bay closed duct rack, so it is the frame you specify for California and other high seismic design areas. It is also UL Listed. Seismic performance still depends on the anchorage and any top bracing being installed per the engineer's detail, so the floor anchors and overhead runway attachment need to follow the approved drawing.

An open frame rack is a four-post-style steel frame with no doors or side panels. You get full access to cabling from all sides and better free-air cooling, which is why telco and network bays use them. A cabinet gives you lockable doors and dust protection instead. Pick the open frame, like this Telco gray B-Line unit, when the room itself is secured and access for patching matters more than physical lockdown at the rack.

The top channel design gives you a structural channel across the top of the frame, which is the mounting point for ladder rack or cable runway and for bracing the bay back to the wall or overhead structure. On a 96 inch tall Seismic Zone 4 frame that top connection is normally part of the bracing scheme, not optional, so order your runway and splice hardware to land on that channel.

Order Eaton B-Line model SB5858096UTG. That number covers the 96 inch tall, 23 inch wide steel open frame with universal 12-24 spacing, 51 mounting spaces, top channel style, Telco gray powder coat, Seismic Zone 4 closed duct network bay.

No cage nuts. The rails are tapped with 12-24 panel mounting holes, so equipment and panels fasten with 12-24 machine screws straight into the rail. Buy the screws, washers and any cable management or grounding kit separately, as they are not part of the SB5858096UTG frame.

Telco gray powder coat over steel is the standard finish on B-Line and most other telecom bays, so it lines up visually with existing telco frames in a typical MDF or IDF. If you are extending a row, match on frame height and rail spacing too: this one is 96 inches tall with universal 12-24 spacing and 51 mounting spaces.
